After officials with Eglin Air Force Base said that a Canadian CF-18 fighter jet likely caused a sonic boom heard and felt in the Mobile Bay area shortly after 8 a.m. Oct. 13, military officials said the jet had been nowhere near Mobile after all.

"They were not airborne at the time, not yet," said Air Force Lt. Col. Michael Neeman, who was hosting the Canadian squad as they ran flight tests from Eglin this week.

The group's test flight was scheduled from 9 a.m. to 1 p.m., and the planes didn't get into the air until about 9:15 a.m., Neeman said.

While an Eglin spokeswoman had mistakenly said Wednesday that the jets were conducting operations in the Whiskey 155 flight space over the Mobile area, the jets were in fact in Whiskey 151, east of Pensacola, Neeman said.

The planes were participating in a "Combat Hammer" weapons system evaluation program, he said.

Residents from central Baldwin County to south Mobile County reported hearing a boom that shook their homes shortly after 8 a.m., county emergency officials said.

Officials with the National Weather Service's Mobile office said there apparently was no local seismic activity to indicate an earthquake, and the sound was not weather-related, though favorable weather conditions could explain why the sound was fairly widespread.
